Concerning my interest in child heath and wellness, I think there is both an objective and a more emotionally-imbued reason. Detaching myself from the emotional aspects of working with and for the sake of children, I am interested in child health because children are constantly growing and developing. In respects to neuroscience, I am able to see and research neurological diseases and cognitive functions as it applies to a brain that is constantly changing. The adult brain does have some plasticity, but it is incomparable to that of a child’s. I am fascinated by the aspect of change and development and how that influences the variables being researched. The emotional reason would be the greater sense of urgency and weight I feel with issues related to children. I believe the best aspect of being young is potential, the ability to become and accomplish almost everything desired. Illnesses and other health-related problems hinder that potential, and I believe effects their future much more than it does in adults. I am interested in this field, because I want to make a contribution to alleviating that hindrance. In high school, I was certain I wanted to pursue a career as a physician. However, as I become more exposed to other opportunities in college, my certainty has dwindled. It could be that my certainty in wanting to only practice medicine was due to lack of exposure to other options. In participating in CRISSP, I want to gain more exposure to research, so I can better…

Cardiac Dysrhythmia Cardiac Dysrhythmia also known as cardiac arrhythmia is a group of of conditions where the heartbeat is irregular and or too fast or too slow. Tachycardia is known as a heart rate that is over 100 beats per minute for adults ,while Bradycardia is too slow with below 60 beats per minute. Majority of arrhythmia issues are not serious, but some predispose one to complications like heart failure or a stroke. Arrhythmia are the leading cause of sudden cardiac death, with 400,000…

In this discussion, I will be discussing a fairly rare cardiovascular disease known as Brugada syndrome. Not only will I discuss the disease itself, but I will also discuss the limited treatment options and the abundant amount of research and scientific facts found by several different organizations on whether or not we can predict the risks of this disease. Brugada syndrome is a disease that is characterized by an abnormal heartbeat. This cardiovascular disease mostly occurs in the later years…

Elaborative Rehearsal and Cardiac Arrhythmias The process of memory is encoding, storing and retrieving information. The information is processed using visual, semantic, or acoustic ques. Maintenance and elaborative rehearsal are storage codes used to store the encoded information. Elaborative rehearsal is “elaborating” on the definition of the word using semantics, acronyms, or acoustic syllables. To adequately retrieve the information, you have encoded and stored you must use proper retrieval…

A Group Case Study on Sam the Runner Presented by: Jaclyn Kerby Meagan Greathouse Krista Young Erin Lofton Suzauna Adams Glossary Arrhythmia: occurs when the heart no longer beats in a pattern considered regular or normal. Cardiac arrest: the sudden loss of heart function, breathing and consciousness caused by abnormal or irregular heart rhythms (ex: ventricular fibrillation) Cardiomyopathy: a disease of the heart muscle (myocardium), may be acquired or…

The ECG/EKG When most people think of heart tests, they think of the ECG. ECG stands for electrocardiogram. It's also called an EKG, from the German elektrokardiogram. Although it may look like an ECG is recording heartbeats, it's not. In fact, it records the electrical activity (the electrical triggers, if you will) that presage the actual heartbeat. The mechanical beats follow the electrical triggers by about a tenth of a second -- unless, of course, there's a problem. Or to state it in…

Cardiac Arrhythmia is an anomaly in the Heart which can be diagnosed with the help of Electrocardiogram (ECG) signal. ECG signal is a diagrammatic representation of the cardiac signal, which is most important biomedical signal, taken for the feature extraction. Since it is very difficult to analyse the ECG signal due to the size, noise and changes in the signal, automatic system for ECG signal processing is essential. For this, ECG signal is processed using wavelets based signal processing,…

Once the P wave initiates the signal, the R wave is the first upward deflection after that. Anyone can easily recognize it on the electrocardiogram (ECG). That is because it is the largest one out of all the waveforms. The R wave corresponds to the depolarization of the left and right ventricles. It does not need the Q wave to be the first deflection at all. Also, note that there can be multiple R waves. Throughout the paper, it will discuss all the wave functions, specifically the R wave, any…

In this paper you will find information about pacemakers and defibrillators. Pacemakers and defibrillators are devices that help keep the heart in rhythm. If the heart starts to beat to slow or to fast it will send an electrical shock to get it back on pace. When you get one or both devices implanted in you will need to have regular check-up with the doctors, these should not affect your daily life. Later on in the article you read that you may be allowed to still participate in fast paced…

A growing number of non-cardiac drugs have been found to delay cardiac repolarization, causing QT interval prolongation and predisposing patients to an increased risk of potentially fatal ventricular arrhythmias, known as torsade de pointes (TdP) (Letsas et al, 2007; Yap and Camm 2003; Sanguinetti and Tristani-Firouzi). These drugs include the second-generation, non-sedating antihistamines astemizole and terfenadine, withdrawn from the market in Europe and the United States (in 1997 and 1999,…
